    <p>I'm trying to use the SQL Server 2008 Change Tracking feature. Once the feature is enabled, you can make use of the <code>CHANGETABLE(...</code> function to query the change tracking history that is kept internally by SQL Server, e.g.:</p> <pre><code>SELECT CT.ID, CT.SYS_CHANGE_OPERATION, CT.SYS_CHANGE_COLUMNS, CT.SYS_CHANGE_CONTEXT FROM CHANGETABLE(CHANGES dbo.CONTACT,20) AS CT </code></pre> <p>where the SYS_CHANGE_CONTEXT column records the <code>CONTEXT_INFO()</code> session value. This column is useful for auditing who changed what etc.</p> <p>Some of the statements that change data are executed using four-part notation by a remote SQL Server that has the home server as a linked server e.g.:</p> <pre><code>INSERT INTO [home server].[db name].[dbo].[CONTACT](id) values(@id) </code></pre> <p>My problem is that the CONTEXT_INFO() as set on the remote server in the session executing the query does not get picked up in my home server change tracking, i.e. it doesn't look like the CONTEXT_INFO spans a distributed query. This means that the following will <strong>not</strong> result in the CONTEXT_INFO being logged on the home server change tracking. </p> <pre><code>-- I'm running on a remote server WITH CHANGE_TRACKING_CONTEXT (0x1256698477) INSERT INTO [home server].[db name].[dbo].[CONTACT](id) values(@id) </code></pre> <p>Does anyone know whether this is a limitation or if there is a way to persist/communicate CONTEXT_INFO across the distributed query?</p> <p>Thanks </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
